long have formed on this tree, and have occasionally matured. It is one 

 of the most striking of pinnate-leaved trees. 



J. MANDSHURICA, Maxtmowicz. 



A tree 50 to 70 ft. high ; young shoots very stout, and like the common 

 stalk of the leaf, clothed with brown, glandular hairs. Leaves i^ to 2 ft. 

 (in vigorous young trees 3 ft.) long, composed of eleven to nineteen leaflets, 

 which are oblong, taper-pointed, finely toothed, obliquely rounded or slightly 

 heart-shaped at the base ; 3 to 7 ins. long, I \ to 2^ ins. wide. When young, 

 both surfaces are furnished, the lower one especially, with starry tufts 

 of down, much of which afterwards falls away from the upper side. Male 

 catkins 4 to 10 ins. long, slender, pendulous. Fruits clustered several 

 on a stalk, roundish ovoid, if ins. long, covered with sticky down. Nut 

 deeply pitted and grooved, i^ ins. long, abruptly pointed at the top. 



Native of Manchuria, especially in the regions of the Amur and Ussuri 

 rivers, and of N. China ; first introduced by Maximowicz to St Petersburg. 

 As a young tree it is, like J. cordiformis and Sieboldiana, remarkably striking 

 in the size of it leaves. It is closely allied to the latter, but in my experience 

 does not succeed so well ; botanically, the chief difference is in the form 

 of the nuts, and the leaves of J. mandshurica are distinctly more slenderly 

 pointed. 



J. NIGRA, LinntZUS. BLACK WALNUT. 



A tree 80 to over 100 ft. high, with a wide-spreading head and a tall 

 dark trunk, with deeply furrowed bark ; young shoots downy. Leaves 

 i to 2 ft. long, composed of eleven to twenty-three leaflets, the terminal 

 odd one often absent. Leaflets fragrant when rubbed ; 2 to 5 ins. long, 

 f to 2 ins. wide ; ovate or oblong lance-shaped, obliquely rounded at the 

 base, long and taper-pointed, unevenly toothed, glossy and smooth above 

 except when quite young, downy beneath ; common stalk minutely downy. 

 Male catkins 2 to 4 ins. long. Fruit globose or slightly tapered at the 

 base, solitary on the stalk or in pairs, i^ to 2 ins. thick, not downy. Nut 

 I to i^ ins. across, broader than long. 



Native of the eastern and Central United States ; introduced early in the 

 seventeenth century. Next to the common walnut this is the best known 

 in the genus. Its nuts are of no value as food, but it is a more ornamental 

 tree than J. regia, thriving almost as well in this country as in any of its 

 native haunts. Trees over 100 ft. exist ; the largest I have seen stands 

 in Marble Hill Park, a magnificent tree with a trunk 5 yds. in girth. As 

 a young tree the black walnut is particularly handsome, with its shapely 

 pyramidal habit and large pinnate leaves. One of the most valuable of the 

 world's timber trees, it is now becoming rare in a wild state. 



Var. ALBURYENSIS, Jackson, an interesting variation from the type, grows 

 at Albury Park, near Guildford ; this bears its fruits in clusters like J. cinerea, 

 sometimes as many as six together, and it is also distinct in its pendulous 

 branches. 



J. REGIA, Linnaus. COMMON WALNUT. 



A tree 60 to 100 ft. high, with a rounded, spreading head of branches ; the 

 bark of the upper branches smooth and ash-coloured ; young shoots without 

 down. Leaves somewhat acrid-scented when rubbed, usually 8 to 12 ins. long, 

 on vigorous young growths 18 ins. ; composed mostly of five or seven, some-
